Methylation Pathway

1. The excretion of 1-methylimidazole-4-acetic acid (MeIAA) in urine was measured in three groups of asthmatic children (acute-symptoms, quiescent and steroid-treated) and a control group of hospitalized non-asthmatic children all on the same restricted diet. 2. There was no statistical difference between the excretion of MeIAA in urine in any of the groups. There was therefore no evidence of impairment of the methylation pathway of histamine metabolism in asthma.

We investigated the change of tryptophan-niacin metabolism in rats with puromycin aminonucleoside PAN-induced nephrosis, the mechanisms responsible for their change of urinary excretion of nicotinamide and its metabolites, and the role of the kidney in tryptophan-niacin conversion. PAN-treated rats were intraperitoneally injected once with a 1.0% (w/v) solution of PAN at a dose of 100 mg/kg body weight. The collection of 24-hour urine was conducted 8 days after PAN injection. Daily urinary excretion of nicotinamide and its metabolites, liver and blood NAD, and key enzyme activities of tryptophan-niacin metabolism were determined. In PAN-treated rats, the sum of urinary excretion of nicotinamide and its metabolites was significantly lower compared with controls. The kidneyα-amino-β-carboxymuconate-ε-semialdehyde decarboxylase (ACMSD) activity in the PAN-treated group was significantly decreased by 50%, compared with the control group. Although kidney ACMSD activity was reduced, the conversion of tryptophan to niacin tended to be lower in the PAN-treated rats. A decrease in urinary excretion of niacin and the conversion of tryptophan to niacin in nephrotic rats may contribute to a low level of blood tryptophan. The role of kidney ACMSD activity may be minimal concerning tryptophan-niacin conversion under this experimental condition.

AbstractBackground To evaluate sulfentanyl combined with dexmedetomidine hydrochloride on postoperative analgesia in patients who received video-assisted thoracic surgery (VATS) and its effects on serum norepinephrine (NE), dopamine (DA), 5-hydroxytryptamine (5-HT), and prostaglandin (PGE2).Material and Methods Ninety-nine non-small cell lung cancer (NSCLC) patients who received VATS were included in the study. All the patients received intravenous inhalation compound anesthesia. Of the 99 cases, 49 subjects (control group) received sulfentanyl for patient controlled intravenous analgesia (PICA) and other 50 cases (experiment group) received sulfentanyl combined with dexmedetomidine hydrochloride for PICA after operation of VATS. The analgesic effects of the two groups were evaluated according to Visual Analogue Scales (VAS) and the Bruggrmann Comfort Scale (BCS). The serum pain mediator of NE, DA, 5-HT, and PGE2 were examined and compared between the two groups in the first 24 h post-surgery.Results The VAS scores for the experiment group were significant lower than that of control group on the time points of 8, 16, and 24 h post-surgery (pall<0.05), and the BCS scores of the experiment group in the time points of 8, 16, and 24 h were significantly higher than that of controls (p<0.05). However, the VAS and BCS scores were not statistical differently in the time point of 1, 2, and 4 h post-surgery (pall>0.05). The mean sulfentanyl dosage was 63.01 ± 5.14 μg and 67.12 ± 6.91 μg for the experiment and control groups respectively with significant statistical difference (p<0.05). The mean analgesic pump pressing times were 4.30 ± 1.31 and 5.31 ± 1.46 for experiment and control groups respectively with significant statistical difference (p<0.05). The serum NE, DA, 5-HT, and PGE2 levels were significantly lower in the experimental group compared to that of control group in the time point of 12 h post-surgery (pall<0.05). The side effects of nausea, vomiting, delirium, rash, and hypotension atrial fibrillation were not statistically different between the two groups (pall>0.05).Conclusion Patient controlled intravenous analgesia of sulfentanyl combined with dexmedetomidine hydrochloride was effective in reducing the VAS score and serum pain mediators in NSCLC patients who received VAST.

Abstract Background Inflammation caused by chronic lung disease in childhood may lead to delayed heart rate recovery (HRR) however, there is lack of evidence on HRR in this population. The aim was to assess HRR after functional capacity testing in asthmatic children and adolescents and to compare with severity and disease control. Method This was a study secondary to a randomized control trial. The modified shuttle test (MST) was performed to assess functional capacity and HRR. This is an externally cadenced test in which the distance walked is the outcome. HRR was assessed after MST and was defined as HR at exercise peak minus HR in the second minute after the end of exercise. Asthma control was assessed by the Asthma Control Test (ACT). Data normality was tested by Shapiro Wilk and the comparison between groups was made by Student’s t test or Mann Whitney test for numerical variables, and by Chi-square test for categorical variables. Statistical significance was considered when p < 0.05. SPSS version 20 was used in the analyzes. Results The sample included 77 patients diagnosed with asthma (asthma group - AG) who were regularly treated for asthma. Control group (CG) consisted of 44 volunteers considered healthy, matched in age and gender to AG. The median age of CG was 12 (10–14) years and in AG 11 (9–13 years) being classified as mild to moderate asthmatic, and 57% of the sample had controlled asthma by ACT. Distance walked in the CG was 952 ± 286 m and AG 799 ± 313 m, p = 0.001. HRR was more efficient in CG (79 ± 15 bpm) compared to AG (69 ± 12 bpm), p = 0.001. The mild (69 ± 12 beats) and severe (72 ± 15 beats) AG presented worse HRR compared to control group (79 ± 15 bpm), p < 0.05. Conclusions Asthmatic children and adolescents have delayed HRR after modified Shuttle test compared to their peers, suggesting that asthma leads to autonomic nervous system imbalance.

1 Biochemical markers of kidney damage were examined in 16 female workers chronically exposed to tetrachlorethylene (TCE) in five dry-cleaning shops. The results were compared with those obtained in 13 females non-occupationally exposed to organic solvents. 2 The intensity of exposure was monitored by personal environmental monitoring. The time-weighed average exposure to TCE amounted to 157 mg m-3 (range 9-799 mg m-3). A satisfactory agreement was found between the concentration of TCE in ambient air sampled with the charcoal tube method and with a passive dosimeter. 3 The urinary excretion of lysozyme was increased in the exposed group. No difference was found in the urinary excretion of albumin, β2-microglobulin, lactate dehydrogenase, total proteins or glucose. The prevalence of abnormal values of biochemical parameters in the exposed group did not differ from that observed in the control group. No correlation was found between the level of TCE exposure and biochemical parameters. 4 The present study suggests that chronic exposure to TCE does not lead to renal damage.

Abstract Background For decades, health providers have worked to manage labor actively and safely, with the goal of shortening the duration of painful labor. Reduction of cesarean sections and maternal complication is also an important aspect of labor management. Antispasmodic are commonly administrating during labor in both developing and developed countries, although there is a paucity of scientific reports validating this. Hyoscine butylbromide is an effective antispasmodic drug. Therefore, We aim to assess efficacy of Hyoscine butylbromide on rate of vaginal delivery in cases of 2ry arrest of cervical dilatation. Objective To assess whether the intravenous injection of hyoscine butylbromide is effective in progress of labor in which cases with 2ry arrest of cervical dilatation. Patients and Methods The study included 100 pregnant women (PG, P1, P2, P3) conducted at Ain Shams University Maternity Hospital, the inclusion Criteria were: term uncomplicated singleton pregnancy in a spontaneous active labor, with cephalic presentation. The patient must be free from any medical disorder associated with pregnancy and free from any obstetric complication. Cases were subdivided into 2 groups: Study group: 50 patients received 40mg iv Hyoscine Butylbromide (as Buscopan 20mg\mrl) when the cervix &gt;4cm dilated and was &gt;50% effaced. Control group: 50 patients received 2ml saline as placebo. Results Significant increase in vaginal delivery rate (72%) in Hyoscine group; compared to Saline group (52%); with significant statistical difference (p = 0.04). Highly significant decrease in 1st and 2nd stage labor time in Hyoscine group; compared to Saline group; with highly significant statistical difference (p &lt; 0.05 respectively). These results observed without significant difference as regards 3rd stage labor time and postpartum hemorrhage (p &gt; 0.05), APGAR score and NICU admission (p &gt; 0.05). Conclusion From the current study we can conclude that HBB 40 mg is safe and effective in increasing vaginal delivary rate in cases of 2ry arrest of 12 dilatation. It is effective in decreasing first and second stage of labor. It has no maternal or neonatal adverse effect. It is easy and available.

This study aimed to determine the occurrence of Candida spp. in the oral cavity of predominantly breastfed infants and in their mothers' mouths and breasts, as well as in the oral cavity of bottlefed infants and in non-lactating women. One hundred and sixty nine women and eighty-five milk-fed infants took part in this study and were divided into four groups: 1) infants predominantly on breastfeeding (n = 55) and their mothers (n = 55); 2) infants on bottlefeeding (n = 30); 3) non-lactating women on whom oral collections were performed (n = 80) and, 4) non-lactating women on whom breast collections were performed (n = 34). Oral and mammary swabs were cultured on Sabouraud agar dextrose with chloramphenicol. The Candida yeast strains found were isolated and identified through morphological and biochemical tests. Candida species were much less frequent in infants who were predominantly breastfed than in those who were bottlefed. Yeasts were much more frequent on the breasts of lactating women, with statistical difference in relation to the control group.

Methanolic Extracts

The aqueous and methanolic extracts of Rumex bequaertii leaves were investigated for their ability to prevent and treated ulceration of the gastric mucosa in animal models.For this, adult male rats three to four months old and weighing on average 180 g were used for both tests. The extracts were tested orally at doses of 125, 250 and 500 mg/kg, on ulcerations experimentally induced by HCl/ethanol and pylorus ligation (acute ulcer) and acetic acid (chronic ulcer).These extracts showed protective and healing properties on ulcer induced models. A dose of 500 mg/kg of the two extracts inhibited ulceration induced by HCl/ethanol by 98.86 and 91.59 % respectively. With pyloric ligation, no significant variation of the volume of gastric juices, pH and gastric acidity was observed compared to the negative control rats. The aqueous extract alone at different doses presented a significant reduction of the ulceration surface resulting from chronic ulcer induced with acetic acid compared to the negative control group that received distilled water. For all three models of gastric ulcer induction used, the mass of mucus significantly increased in the groups that received the extracts. There was no significant variation in plasmatic nitric oxide (NO) concentrationand gastric supernatant of rats treated with both extracts compared to both control groups. These results reveal that the healing process of the extracts is not achieved through the NO pathway. This process could be due to increase in mucus production and thus supports its traditional use of the plant
